The C7A1 5.56 mm assault rifle.
The C7A1 5.56 mm assault rifle.

The C7A1 is a 5.56 mm assault rifle that remains unused by any faction in ArmA 3. It was added with the release of the Global Mobilization - Cold War Germany Creator DLC.

Overview[]

This section is a stub. You can help Armed Assault Wiki by expanding it.

The C7A1 is a selective-fire assault rifle with a direct impingement operation that is chambered to fire the 5.56×45 mm NATO round.

It feeds from 30-round STANAG magazines but can also load older 20-round box magazines utilised by the M16A1. It can attain a fire rate of up to ~ 652 on semi-auto[CfgWp 7][Formula 1] or 800 RPM on full auto.[CfgWp 8][Formula 2] C7A1s have a muzzle velocity of 960 m/s.[CfgWp 9][Formula 3][note 1]

The C7A1 supports being fitted with optical sights, IR/visible laser pointers, flashlights[CfgWp 10], and 5.56 mm sound suppressors.[CfgWp 11] However, it is not able to mount a bayonet nor a bipod, and is also unable to have a laser pointer/flashlight mounted at the same time with an optic (they occupy the same rail used by optics).

Ironsights[]

Arma3-gmcwgc7a1-ironsight-overview

The C7A1's ironsights can be manually zeroed starting at a minimum of 100 metres up to a maximum of 400 metres (100, 200, 300, 400).[CfgWp 12] By default, it uses a zeroing of 300 metres.[CfgWp 13]

If an optical sight with a zeroing limit greater than 400 metres is fitted, the C7A1 will permit a maximum zeroing of 800 metres.[CfgWp 14]

Camouflage[]

  • Black: All-black finish.
  • Olive: Standard matte black finish with an olive green-coloured handguard and stock.

Ammunition[]

NOTE: The C7A1 is capable of loading the same magazines utilised by non-Global Mobilization 5.56 mm-chambered weapons. To minimise clutter, they are deliberately excluded from this section.

The C7A1 is able to load up to eight types of magazines, all of which are fully shareable with every rifle platform that is based on the AR15 family of weapons.[CfgWp 15] Its 30-rounder STANAGs have a weight of 12.2444 "mass" units[CfgMa 11][CfgMa 12] while the older 20-round box magazines weigh 7.77778 "mass" units instead.[CfgMa 13][CfgMa 14]

It should be noted that these magazines are not interchangeable with the G36, G33, and SG550:

It should be noted that magazines from other Creator DLCs that share access to the same pool of magazines (Classnames: STANAG_556x45 / STANAG_556x45_Large) can also be loaded into the C7A1. However, those Creator DLCs must be loaded simultaneously alongside Global Mobilization - Cold War Germany in order for them to appear as selectable options in the Virtual Arsenal.


Trivia[]

  • The C7A1 was not initially available on Global Mobilization's release and was only added after Update 1.1.[1]
  • Following Update 1.4's release, the C7A1 is now able to load 150-round drum magazines that were added in ArmA 3's Apex expansion.[2]
    • The patch also included two "new" magazines loaded with older M196 tracer rounds (only magazines loaded with M193 non-tracer ammunition were available prior to the update).[2]
  • Update 1.6 corrected issues with the C7A1's range limits and dispersion values for the AI. Prior to the patch's release, AI units with C7A1s shared the same dispersion values with human players, allowing them to hit targets with pinpoint accuracy at any distance.[3]
The information below details unused, pre-release or removed content.
  • Curiously, a separate olive green-coloured variant with a brighter handguard/stock exists within the DLC's files (Texture name: gm_c7a1_ext_01_grn_co.paa[4][5]) but remains unused for unknown reasons.
    • It also has a unique text string identifier that would have been used to designate this variant (String name: STR_DN_GM_C7A1_GRN[6]).

Formulae

  1. 60 / reloadTime = 60 / 0.092
  2. 60 / reloadTime = 60 / 0.075
  3. Weapon's initSpeed * Magazine's initSpeed = 1 * 960
  4. initSpeed * caliber * 15 / 1000 = 960 * 0.73 * 15 / 1000
  5. initSpeed * caliber * 15 / 1000 = 960 * 0.73 * 15 / 1000
  6. initSpeed * caliber * 15 / 1000 = 960 * 0.7 * 15 / 1000
  7. initSpeed * caliber * 15 / 1000 = 960 * 0.7 * 15 / 1000

Notes[]

  1. The C7A1's muzzle velocity is determined by the magazine's initSpeed value (the weapon itself only applies a multiplier).
  2. 2.0 2.1 2.2 2.3 Damage will be reduced if the projectile's velocity drops below this value.
